Electronic Pen Local Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic pen systems require pre-stored templates and external system components to be accessible for data processing, leading to dependency issues and potential data loss if any part of the communication chain fails.
Innovation Solution
The electronic pen can derive and store input data from a second code on the product, allowing it to process position data independently and asynchronously, reducing dependency on external components and enabling secure, asynchronous data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the electronic pen uses pre-stored templates and external system components for data processing, then data processing capability is improved, but system reliability deteriorates due to dependency on external components and communication chain failures
Solution Approach 1:
The electronic pen is equipped with a processor and memory that enable it to independently process position data and derive input data without requiring continuous communication with external systems. The pen can store and process templates locally, and the processor can autonomously convert position data to application-specific formats, making the system self-sufficient and reliable even when external components are inaccessible.
Solution Approach 2:
The system divides functionality between the electronic pen and external components. The pen handles core processing tasks locally (position data conversion, input data derivation), while external systems provide supplementary support when available. This segmentation allows the pen to operate independently when needed, resolving the contradiction between automation capability and system reliability.
2Measurement precision
If the electronic pen requires external system components to be accessible for data transfer, then data processing refinement is improved, but data availability deteriorates when communication chain components are offline
Solution Approach 1:
The electronic pen pre-derives input data from position data using its local processor and stored templates, before any external communication is needed. This preliminary processing ensures that refined data is already available in the pen's memory, eliminating dependency on external systems for basic data refinement and ensuring data availability even when offline.
3Measurement precision
If the electronic pen stores templates and requires communication with external systems, then processing accuracy is improved, but device complexity increases
Solution Approach 1:
The electronic pen incorporates a processor and memory that enable it to independently execute template-based processing and data conversion algorithms. By embedding these capabilities directly in the pen, the system achieves high processing accuracy without requiring complex external infrastructure, as the pen serves itself for core processing functions.

AI summary
In an information management system for handling digital position data recorded by an electronic pen, the pen is controlled to convert recordings of a first code on a product to position data in a coordinate system, to convert recordings of a second code to input data, and to process the position data on the basis of the input data. The input data may define one or more functional areas in the coordinate system, and the pen may map the position data against the input data and take appropriate action if the position data is deemed to fall within a functional area. This allows the pen to be dynamically provided with a description of all or parts of the functional layout of a product, thereby reducing the need of the pen to pre-store such descriptions for all products. Encryption or usage may also be controlled based on data encoded by the second code. The product may be generated, via a computer-implemented method, to include the first code, the second code and any supporting graphics. The input data may alternatively be derived from another import interface of the pen, such as a communications interface or a replaceable memory unit.
